ELMER. is. :Bui/mus, or KALISP'ELL, MONTANA.

To all whom t nay concern.' v

lc it lknown that4 I, ELMER BUMrUs, citizen "of the United States,` residing at Kalispelh in thepounty of' Flathead and State of`Montana,have invented a new and Vuseful` Hot-AirsCirculating Fireplace, or'

which the following is a specification.

^ Thisinvention relatesto ran improvement in hotair circulating fire places, and the `obiect :is to provide an air space or chambei", between the chimney-and the fire place and flue, for the purpose of utilizing the f r-.heat thrown ofi by the fire place and' the from a room to he air chamber, where it lthrough the iiue as the products ofeombustion Ypass up flue and` chimney. 'Inlet openings are formed in the chimney for 'admit tingair from any suitable source, such-as willbe heated. After the air has been heatling the admission of heat to a` room or ,y rooms. Q i A further ob] the construetionof wherein i the 'sides for the purpose of l ect is in a `removable ire place, and back can be removed i f replacing any `oi* the parts that may become m udefective by warping or g j Another objectis 1n .so

cracking.

the provision ot meansA for supporting ai flue, which is independent of theiire` place, so'that tlievarious sections of the fire pla ce can be removed and pointed departing from The invention consists without affecting the flue. f of certain 4novel "features of construction land combinations oli will be hereinafter described out in the claims.. It` is evident that many sllght changes parts, which `,maybe made in the form and arrangement of the several `parts toglbe described, without invention, and'hence IIdo not wish to be limr ited to the eXact construction herein set l `is a transverse orth. `In the accompanying drawings- Figure vertical sectional view.

A represents the chimney, which may be constructed of .brickjstonm concrete, cement,

and the like. The chimney is provided with -`but in this instance an cnlargedopening is provided in which a re place 1s mounted. The fire place is constructed of a base 1, j'made insections, the two sections being supported by means of posts or standards.y A flange 3 is formed on one'of the sections of the base for forming a tight ioint between the adjoining edges of the two sections.I Parallel flanges 4 are` formed along the rear edgeo the base 1, between which 1s received one Ofthe sections or plates 5 of the back. Each ofthe back platesl 5, `with the eirception of the upper most plate, are provided along`one of their longitudinal-edges with parallel flanges 6.

A longitudinal groove is formed between the parallel flanges of each back. plate, in which groove tlielower longitudinal edge of the `adjacent bers 7 are mounted upon the base 1 and are `held vin position by meansv of flanges formed on the base along .the outeredges thereof. P1ns 9 are adapted toenter openings formed 1n the base for holding" the i Iside members againstthe anges 8 for, supporting 'the sides. The inner vertical edges back plate is received. Side 1nem-V of th'e side members engage the inner faces .f

of tbe several back plates 5. on the back plates engage the exterior surfaces of the side members. Ears 1l are formed on the side members 7 at Suitable intervals, and are adapted to engage the back plates 5. Bolts 12 pass through 'the and flanges l0 ears and back plates.l and nuts 13 are screwed upon the bolts for fastening the side members and back plates together.

Angle iron the chimney, edge thereof, place. An angle iron and extend across the upper bar 16 extendgiacross bars Mare mounted within.

above the opening 15 of the tire the re7place and is engaged by the upper,

terminal of the uppermost back plateA .5. The upper. terminals of the side members] are located between the angle iron bars1l4 and the uppermost back plate 5, so that the side members and back are maintained in `position at their upper terminals by the bars 14 and 16. The flue ,17 is supported upon 110 the bars' 16 and I14, so that` the' products of combustion will pass directly from' the fire place into 'the flue 17.

The base 1 of the fire place is provided with an opening, lwhich is normall closed 1@ permost angle iron bar 14:,and is adapted'to rest upon thebar 16 for closing'the-iue 17. A flexible means, such as ay chain 21, is con! nected to the damper 20, fand extends 4through. thel'ue 17, and a Atube 22 which i5 projects through thebreast oi' frontside of the chimney. A slot 23 is formed in the youter terminal of the tube 22 in which a link of the chain 21 may .be received for holding the damper in an open or partially open po- 2a, sition.

Surrounding'the re place is ana air cham- .ber B, which extends across the back and on both fides of the fire place, as Well as below the iire place. -This air chamber is c0n' tinued for a distance vertically of the chimney and entirely around the flue 17 An outlet conduit 24 is formed in the fireplace for eoipductingthe heat from lthe air chamber toa room, and outlet conduits are formed `in the chimney leading from the vchamber or air space B at various points, as indicated at 25 and 26. These several Openings '24, 25 and 26 are preferably provided With registers 27, which are capable of being regulated for controlling theadmission of heated Vair to the room. Air inletpipes 28 extend through'the fire-place for admitting air to theair chamber B. These inlet pipes 28 may be located at any suitable placein the fire-place for the purpose .of

" y conducting the cold air from a room, o r the atmosphere to the air chamber B.- Wlth a lire place constructed in this manner having an air chamber located therearound, and extending vertically through the chimney and faround the flue, it is possible to utilize the Waste heat fromthe fire place and chimney.

By means of a fire place constructed of a pluralty of sections, as set forth, vwherein f the back is composed of ay plurality of, inter# locking plates, and the side members are removably connected to the back plates, it is possible 'to maintain the entire structure in a rigid condition and to remove any of the back or side plates at any time they become defective caused lby cracking or `warping. The fireplace is independent ofthe fine and canbe taken down and repaired at any time Without disturbing'the flue ordamper.

The surface of the plates 5 is preferably fiat and the plates extend fromv the rear :edgeofthe basel to the lbar, 16at an angle, so vthat the heat Will bedelected'. into the `room but the products of combustion will be causedto pass into the Hue 17 tions., l e f I l 6. rThe combination with a chimneyhav- What is claimed, is,ir

at its lower end, a removable back placed in the chimney, removable sides detachably en- A gagingy the back, a damper hinged in the chimney'at the top of the sides and back,

f and an angle bar arranged transversely in the chimney engaging the back and sides port said damper when turned down into closed position. t

2. In combination with achimney open at its lower end, a .removableback placed Within the chimney, removable lsides detachably connected kto the back, a' fiue extending upwardly in the chimney, a damper hinged in the chimney at the bottom of the iiue, and an angle bar arranged transversely in thel chimney to support the upper ends of 'said back and sides, to support said flue and munication with the fire place supported` upon said bars, means for controlling the admission ofl the products of combustion to the flue, said chimney provided with outlets for conducting the heated air from the air chamber. f

4. The -combination of a chimney having an opening therethrough, a fire place mounted therein,'fconsisting of a base, side mem- -to support the same, and adapted `to supbers and back plates, angle iron bars mountedin the chimney beingfengaged by the side members and back plates for supporting them,`and a flue in communication withv the fire placeAv mounted on said bars independently of the side members and back plates of the fire place, whereby the lire place can be repaired Without removing the flue.

5. In combination with a chimney openat rits lowerend, of a lire place spaced inwardly from? the walls of the chinmey,'and a flue leading upwardly through the chimney in spaced relation to the Walls thereof from the ire place, saidre place comprising a plurality ofvseparable sections, and a vtransverse bar in the chimney atr the bottom of the `-flue for supporting the said sectiensy when assembled and for ysupporting' sid flue and frelieving the weight thereof from said sections, -said transverse `bar `adapted tov support'theue during-the removal and vadjustment ofsaid tire place secg `an opening, of a re place mounted as my own, have hereto ailxed my signathereln consisting of a base, side membersr ture in the presence of two witnesses.
